SEA SQUIRTS
(Posted 2009-03-16 10:40:20 by ArchPaladin)

I have just found out about an animal called a tunicate [
http://en.wikipedia.org/wiki/Tunicate ] [wikipedia.org], which also goes by
the colloquial name "sea squirt".  Apparently this creature spends half of
its life motile, searching for a good rock on which to attach, and then the
other half of its life is spent sedentary, attached to the rock as a filter
feeder.  What makes this particularly interesting is that once it has
attached itself to its new home, it consumes its own brain and nervous
system that allowed it to move there in the first place.

I think this has an interesting spiritual corollary: don't ever get to used
to where you are, because you'll lose the ability to adapt out of it.
